3. General instructions
3.1 General instructions
Oil burners must be installed in accordance with local regulations. The
installer must therefore be knowledgeable of the regulations pertaining to oil
and combustion.
Only oil suitable for the burner must be used and then in combination with a
suitable oil filter installed before the burner’s oil pump.
If the burner is replacing an existing burner, ensure that the oil filter is
replaced or cleaned. Installation may only be performed by qualified
personnel.
Care should be taken by the installer to ensure that electrical cables and oil
lines are not pinched or otherwise damaged during installation or servicing
3.1.1 Installation and Maintenance Manual
The maintenance instructions supplied with the burner must be kept at an
easily accessible location in the boiler room.
3.1.2 Instructions
The user must be comprehensively instructed in the operation of the oil
burner and entire system. It is the responsibility of the supplier to instruct the
user.
3.1.3 Inspection and maintenance
Refer to servicing schedule
3.1.4 Start-up
In order to obtain the correct setting, a flue gas analysis and temperature
measurement must be carried out. Otherwise, there is a risk of soot build up,
poor efficiency or condensation in the chimney. The system must be fine-
tuned at start-up. The temperature in the chimney at a depth of 0.5m must
be at least 60°C to prevent condensation.

12 Bentone
!If any electrical connection is used other than that recommended by Enertech, there may be a risk of
damage to property and personal injury.
3.2 Delivery inspection
Make sure everything is delivered and the goods have not been damaged
during transit. If something is wrong with a delivery, report it to the supplier.
Transport damage must be reported to the shipping company.
3.3 Preparing for installation
Check that the burner’s dimensions and capacity range are suitable for the
relevant boiler. The power data on the rating plate refers to the burner’s
minimum and maximum power.
3.4 Oil distribution
In order to achieve good reliability, it is important that the oil distribution
system is designed correctly.
Take the following into account:
-Selection of pipe diameter, pipe length and height difference; see
Pump instruction.
-Pipelines are to be laid with the fewest possible number of glands.
-The pipes are to be laid so that the oil supply hoses are not subjected
to tensile stresses or become excessively bent when the burner is
swung out or removed for servicing.
-The oil filter should be installed so that the filter cartridge can easily be
replaced or cleaned.
-Parts in contact with oil must be selected in materials that are capable
of withstanding the medium’s physical properties.
-When installing oil hoses, check that the inlet and return hoses are
fitted to the appropriate connection on the oil pump. The hoses must
be located so that they do not bend or become subject to tensile
load.
-Bleed the oil system. The oil pump/oil preheater may be damaged if
run dry. The vacuum in the suction line should not fall below 0.3 bar
during start-up.
!Be sure to fill the
burner oil system
before starting it for
the first time.
3.5 Electrical connection
• Before work on the electrical connection, the current must be
disconnected so that the installation is isolated.
• Electrical connection must be done in accordance with the applicable
regulations.
• Burners must be connected to an all-pole switch.
• Connection must conform to the wiring diagram.
• Use appropriately sized fuses.
!The oil filter must
be installed before
the burner’s oil
pump

3.6 Burner installation
3.6.1 Hole pattern
Make sure the hole pattern on the burner corresponds to the supplied flange
(refer to Technical data).
3.6.2 Burner installation
1. Install the flange with gasket on the boiler.
2. Fit the selected nozzle
(refer to Technical data).
3. Install the brake plate and check the ignition electrodes
(refer to Burner Servicing).
4. Mount the burner to the flange.
5. Insulate between the burner and boiler door to reduce radiated heat (if
necessary).
3.6.3 Oil lines
1. Check the dimensions of the oil lines (refer to Pump instructions).
2. The oil filter should be fitted to the incoming oil line. If a degasser is
installed, the oil filter should be fitted to the oil line up to the degasser
in order to prolong the service life of the oil filter.
3. For single pipe systems, the return plug must be removed
(refer to Pump instructions).
4. When installing oil hoses, check that the supply and return hoses are
fitted to the appropriate connection on the oil pump. The hoses must
be located so that they do not bend or become subject to tensile load.
5. Bleed the oil system. Dry running will damage the oil pump.
6. The vacuum in the suction line should not fall below 0,3 bar during
start-up.
3.6.4 Electrical connection
If the boiler does not have a pre-fitted connector, connect to the supplied
connectors (x2) as shown in the wiring diagram.
1. Switch off the main switch.
2. Connect the Europlugs (x2) as shown in the wiring diagram.
3. Fit the Europlugs (x2) to the burner.
4. Turn on the main switch.
3.6.5 Check oil line seals
Once the burner has been installed and commissioned, the seals of the
various coupling elements should be checked.
When a leak is detected, it is usually sufficient to tighten the coupling
element that is leaking.

4.2 Suction plate
In the case of higher power, as well as with boilers featuring overpressure
in the combustion chamber, it is possible to achieve higher fan pressure by
altering the position of the suction plate, see illustration. The plate is located
beneath the outer half of the fan housing, see illustration, Cleaning the fan
wheel.
-Position 1 is normally used for nozzles up to 0.60 gph and position 4
for larger nozzles. Position 2 and 3 are intermediate positions. Positi-
on 5 and higher does not give more pressure and they are not used.
-Check that the plate is placed in the correct position. Otherwise the
aircannot be adjusted to the correct value.
4.2.1 Insert control
The burner is equipped with a lever that changes the position of the brake
plate in the burner tube. This is used to set the correct pressure drop across
the combustion assembly, thereby obtaining good combustion without
pulsation.
The setting to be used depends on, among other things, the output settings
and overpressure in the boiler
Setting the brake plate
• Small column: turn the screw left
• Large column: turn the screw right
Setting the brake plate position affects airflow. Therefore, it is always
necessary to fine-tune airflow using the burner’s airflow regulator.
4.2.2 Air intake adjustment
Setting the air intake is very important to achieve good combustion with
neither too much nor too little air. To adjust the combustion airflow, turn the
airflow knob lever. The extent to which the airflow lever must be open is
determined by the heat output and overpressure in the boiler as well as other
settings on the burner such as the position of the brake plate.
4.2.3 Setting the air quantity
Turn the air intake clockwise to increase airflow and anticlockwise to
decrease airflow. Insert control Air control

!When servicing/replacing components that affect com-
bustion, an analysis and soot test must be carried out on
the installation.
5. Burner servicing
5.1 Servicing
Servicing must be carried out after 3,000 operating hours, but at least once
yearly.
Only authorised personnel may perform service.
Before any type of servicing is carried out, shut of the power at the main
switch and turn off the oil.
Be careful: certain parts exposed after separation of the burner can be hotter
than 60°C. Care should be taken by the installer to ensure that electrical
cables and oil lines are not pinched or otherwise damaged during installation
or servicing.
5.2 Hanging the burner
